squeeky key?

my "i" key on my mbp is squeeky. thats the only way i can think to describe it. its not loose or anything, but just noisy for some reason. its not a huge problem or anything, definitely something i could live with if there isnt an easy fix, but with applecare is this something that would be covered?
